6 Claims.

This invention relates to manifolding, and, more particularly, to themethod of making continuous piles, including interleaved record andtransfer strips, and to a novel form of transfer strip.

Heretofore, it was proposed to zigzag fold the record and carbon stripsand then bring the folded strips together so that the carbon strips areinterleaved with the record strips and the foldson the two kinds ofstrips are nested one within the other.

It was also proposed, heretofore, to provide the line of severancebetween the record strip and the transfer strip in such a way that whena set of strips is severed from the pile of continuous strips along thefold lines which are usually weakened, a tab will be provided on one endof the carbon while a notch, from which a similar tab was removed, isprovided on the other end of the carbon. The tab portion, in

adjacent form by a tit or narrow band of material so that the ;tabportion would fold. with. the

adjacent form to which it is attached. In many' cases, it is desirableto havethe tab in the carbon' completely out from the adjacent form,but, in interleaving and refolding such carbon strips with the recordstrips, it was diillcult to keep the tabs from folding on themselves, so-that they would not project beyond the edges of the record strips asthey are intended. The present invention has solved this problem by themaking of a novel and improved form of carbon strip supply for use inmaking up interleaved continuous record and carbon-strips. According tothe present invention, instead of attempting to fold the tab portion ofthe carbon strip, it is allowed to remain unfolded, the carbon stripbeing folded on a weakened fold line, 'a continuation of which would gothrough the tab. I have found that with the tab on the carbon stripunfolded and uncreased, when it is interleaved between the record stripsand thelatter are folded on their weakened fold lines, the tab becomesfolded and is prevented by the interposed strip material from foldingdirectly on itself. The result is that, when the strips are torn alongthe weakened fold lines the tab will always project beyond the recordstrips and not many instances, has been left attached to the tab at theother end of the pile of sheets inwardly removed from the adjacent edgeof the record lie folded on the carbon sheet to which it is attheadjacent margin of the sheet from which it tab portion creased duringthe operation of 'interleaving the carbon strip with the record strip.Other features and advantages will hereinafter appear.'

In the accompanying drawing which illustrates the present invention- IFigure '1 is a perspective view of a zigzag folded carbon strip madeaccording to the present invention. I

tion of collating the record and carbon strips.

Fig. 5 is a sectional view, showing the position m of the pack in thefolded pile of record and transfer V strips.

' As shown in Fig. 3, the manifolding pack of the present inventioncomprises a plurality of record strips l0 interleaved with one or moretransfer 25 strips ll, and folded zigzag along weakened fold lines It toform a zigzag folded pack I3 froni which the leading or top end of thepile may be taken and introduced into a typewriting machine.

As previously proposed, the carbon strip is so 30 arranged as to have atab l4 projecting beyond the adjacent edges I! of the record strips atone end of the pile of sheets severed from the pack 13, and a notchcorresponding in shape to the sheets, so that, when the carbon tabs Itare grasped by the fingers of one hand, and the record sheets aregrasped by the fingers of the other had over the notched portion of thecarbon sheet, pulling of the hands apart will strip all of the carbonsfrom all of the records. The records and carbons are folded atsheet-length intervals along transverse lines of weakness l6, and thetab on one sheet length of the transfer strip is taken from the adjacentend'of the next sheet length of the transfer strip.

united to the sheet length of the carbon strip within which it lies,there being ties, or even a single tit, between the margins of the taband is formed.

In this situation, when the carbon strip is taken from a zigzag foldedpile to be interleaved with similarly folded record strips, the tab alsounfolds and has no opportunity of remaining folded upon itself as thecarbon goes between the record strips and the pile is refolded.Therefore, the tab will always project beyond the edges of the recordstrips when a set of sheets is torn off from the pile along the foldline.

In many instances, it is desirable to have the tab formed by anincision, so that it is entirely free from the sheet length from whichit was formed, to reduce the chance of the tab being inadvertently tornoff in the severing operation. In this case, great difficulty has beenencountered in keeping the tab from being folded over on itself at thetime when, as in Fig. 2, the record strips l0 and carbon strips II arebeing collated and refolded into a single pack.

According to the present invention, this difliculty is obviated by sopreparing and forming the tab and the resulting notch that the tab isnot folded in a zigzag folded pile of carbon strips. As shown in Fig. 1,the tab I4 is formed by an incision intersecting the weakening line 16in the carbon strip, and so folding the carbon strip that the tab H isnot folded but lies in the plane of the sheet length to which-it isattached. Preferably, although not necessarily, the weakening line l6does not extend across the'tab, and hence the tab remains anuninterrupted continuous part of the sheet length to which itbelongs.

The carbon pack, illustrated in Fig. 1, may be made up and sold as suchto be collated with record strips similarly divided into sheet lengths.When the carbon strip is, as diagrammatically illustrated in Fig. 2,collated with zigzag folded record strips, the uncreased tabs I4 willlie in the pile substantially as shown in. Fig. 4, projecting straightinto the space between the next sheet lengths of the upper and lowerrecord strips l0 which have their creases I! in register with thecreases I8 in the carbon strip. Then, when the pile of strips is folded,the base of the tab will always be folded'to correspond with the creasesII in the record strips and the tab will occupy the position'shown inFig. 5, having returned to the notch l9 from which it was cut originallyand being prevented by the interposed record strip I0 from foldingdirectly upon itself, where it would not be in position to be graspedwhen the set of written forms is severed from the pile.

It will thus be seen that the carbon strip is folded in two separateoperations, one operation folding the main portion of the strip andbeing done during the manufacture of the pack of continuous carbonpaper, and the other part, i. e., the tab, being folded during theoperation of assembling the record and carbon strips. The carbon stripmaterial being rather thin and not too stiff, the tab I4 is folded bymerely being confined between the folds of the upper and lower recordstrips, which, having previously been creased, automatically assumerefolded condition.

Applying light pressure, as by the harids, to the refolded pack, willdefinitely cause the tab to be creased.

' It should be understood that within the scope of this invention thetab may be of any desired shape and it may be located either at the topof the sheet length or at the bottom and to one side of the center ordirectly on the center as shown, without departing from the presentinvention.

Variations and modifications may be made within the scope of thisinvention and portions of the improvements may be used without others.
